摘要（英）：

The invention relates to a low-temperature liquid degreasing agent, which is mainly applied to a degreasing process step in pretreatment of coating of automobiles and household electrical appliances. The low-temperature liquid degreasing agent is characterized by comprising the following substances in percentage by weight: 2-10% of silicate, 10-40% of basic salt, 1-5% of chelating agent, 2-8% of surfactant and the balance of water. The low-temperature liquid degreasing agent disclosed by the invention has the following advantages: new raw materials which do not contain phosphorus or surfactant and can be biologically degraded are used in the formula of the degreasing agent, so that the environment-friendly requirements can be met; and simultaneously, the degreasing agent can ensure high cleaning property and low foaming property when being used at a low temperature (25-45 DEG C).
